Erratum: Muāraza in Modern Arab Literature: Example of Ahmed Shawqī-Hashim al-Rifāī
No full textAhmed Shawqi is a strong writer who used the classical style of Arabic literature in his poems. He influenced many poets. One of them being Hashim al-Rafai Hashim, who started writing poetry at an early age, left a mark on poetry divan, and made muarazas to some of his poems. In this study the poems of Nahc al-Burda, Mawlid al-Nur and al-Azhar, which are one of the divan literature of Hashim, are examined. These three poems are being discussed in terms of naming, letter of rhyme, rhyme, centroid, content and number of couplets. In addition, this study captures a comparison with of Ahmed Shawqi's poems, furthermore the effect of Shawqi's poems on Hashim's poems are determined. By examining the 20th century examples of the art of muaraza that has existed since the Jahiliyya Period, the effect of the form and content used by a poet in his poetry, come to light on the literal works of other poets

Population studies of a commercially fished bivalve mercenaria mercenaria (L), in Southampton Water
No full textThe hard shell clam Mercenaria mercenaria (L.) is a long-lived animal tolerating wide environmental variations. The animal is an important constituent of the macrobenthic fauna in Southampton Water. A study was made of various aspects of the population in relation to absence of cooling water discharge caused by closure of Marchwood power station, increased fishing activities and the frequent failure of settlement in recent years. The littoral population at 12 sites was sampled in two successive winters. The highest density of clams was at Netley and the lowest at Royal Pier, with actively growing and reproducing populations extending to Solent Breezes and Lee-on-Solent in the eastern Solent. The total stock estimated for littoral sites above Hamble Spit has shown a reduction of about 50% since 1970. The population at present is dominated by large and old individuals originating from settlements in 1971, 1972, 1973 and 1976. These year classes and a recent settlement in 1984 seem to coincide with low river flow during August, September and October of each year. The annual production of littoral Mercenaria populations at both Marchwood and Lee-on-Solent approximated to 3gm-2yr.-1. Although Mercenaria dominates the biomass of the benthic fauna, energetically its role in the ecosystem has been diminished in recent years as a result of change in the population structure towards larger/older individuals. Growth in Mercenaria was analyzed according to the Logistic, the Gompertz and the Monomolecular models. The Gompertz provides an accurate model of ontogenic growth in Mercenaria. Highest predictive growth rate in shell length was found in littoral population at Solent Breezes, Hamble Spit, Weston and Netley. Maximum growth rates in shell length were achieved during the 2nd and 3rd years, whereas maximum growth rates in flesh weight were recorded during the 4th and 5th years, indicating that during the early stages and before gonad maturation a greater proportion of energy is directed to formation of shell rather than in flesh. Monthly gamete counts at Marchwood and Lee-on-Solent permitted assessment of the reproductive cycle, and the consequences of gamete production on variation of growth at both sites were discussed. It appears that at Marchwood a greater proportion of available energy is devoted to gamete production and less to somatic growth than at Lee-on-Solent. The gamete counting also revealed that the peak of spawning occurred at the end of summer and during autumn, this result was supporting data obtained by weekly monitoring of larvae. Results suggest that Mercenaria is capable of spawning at 16oC, which is a lower temperature than that reported in earlier works, indicating a physiological adaptation to local conditions. Growth, survival and environmental factors affecting abundance of planktonic larvae over an 8 days period were studied. It appears that larvae remain in the plankton for about 15 days, at summer temperature. The 12 hours survey of vertical distribution provides evidence that larvae are retained within Southampton Water through behavioural regulation during different stages of the tide. The distribution, seasonal growth and survival of spat throughout the estuary, were investigated. First settlement of the spat in 1984 took place in the latter part of August. The population is seen as stock in decline largely resulting from overfishing and failure of spat settlement in recent years.</p
Synthesis of (Poly-methyl Methacrylate-lead Oxide) Nanocomposites and Studying their A.C Electrical Properties for Piezoelectric Applications
No full textPiezoelectric materials have been prepared from (poly-methyl methacrylatelead oxide) nanocomposites for electronic applications. The lead oxide nanoparticles were added to poly-methyl methacrylate by different concentrations are (4, 8, and 12) wt%. The structural and dielectric properties of nanocomposites were studied. The results showed that the dielectric constant and dielectric loss of nanocomposites decrease with increase in frequency of applied electric field. The A.C electrical conductivity increases with increase in frequency. The dielectric constant, dielectric loss and A.C electrical conductivity of poly-methyl methacrylate increase with increase in lead oxide nanoparticles concentrations. The results of pressure sensor showed that the electrical resistance of (PMMA-PbO2 ) nanocomposites decreases with increase in pressure
Thinking outside the box: unconventional artificial intelligence algorithms in the detection and management of liver cirrhosis
No full textA significant proportion of liver patients present withadvanced stages at the time of diagnosis [1] leading toimpaired prognosis and reduced survival probabilities [2].Unsurprisingly, a diagnosis of cirrhosis is independently asso-ciated with all-cause in-hospital mortality [3]. Current path-ways rely on primary care physicians proactively screeningpatients for hepatic fibrosis using dedicated tools, which canbe suboptimal [4]. Artificial Intelligence (AI) is gaining globalattention in the medical field and beyond, with researchexpanding and evolving exponentially. Hence, leveragingeasily applicable AI models based on widely available routinetests may enhance early detection resulting in timely interven-tion and reduction in mortalit
